SPECIFICATION forming part of Letters Patent No. 668,453, dated February 19, 1901. Application tiled December 20, 1900. Serial No. 40.530. .No model.)

To a/ZZ whom it Netty concern:

Beit known that I, HENRY A. N ETTLETON, a citizen of the United States, residing at Manchester, in the county of Hartford and State ot Connecticut, have invented certain new and useful Improvements in Trolley- Heads, of which the following is a specifica tion.

My invention relates to the class of devices used for receiving a current of electricity from a wire or like means of supply and serving as a part of the means for conveying the fluid to a motor or like part arranged on a vehicle; and the object of my invention is to provide a device of this class more especially designed for use on a trolley-pole by means of which the trolley-Wheel may be readily attached to or removed from the trolley-pole.

A device in connection with which my invention is applicable is illustrated in the accompanying drawings, in which*- Figure 1 is a view in side elevation of a portion of a trolley-head supplied with my improved attaching means. Fig. 2 is a like View showing the latch in its raised position. Fig. 3 is an edge view of the trolley-head supplied With my improved attaching means. Fig. et is a detail View of the trolley-wheel axle or spindle.

A difficulty has been experienced in devices of this class prior to my invention when it is desired to remove the trolley-wheel tor any purpose from the trolley-head, prior devices of this class containing faults in construction whereby the trolley-wheel is not securely held in position or in which considerable laboris involved in removing or attaching the trolley wheel. My invention provides a device in which all of these faults of prior construction are done away with and by the use of which a trolley-wheel may be easily and readily removed or replaced.

In the accompanying drawings the letter a denotes a portion of a trolley-head that may be attached to the trolley-pole after any of the Well-known forms of construction. This Slots as extend from the upper edge of each side part ot the trolley-head fora short distance inward, the bottom of these slots forming a bearing for the trolley-Wheel axle or spindle c. This spindle c has at each end and on opposite sides thereof retaining-grooves c', adapted to receive the edges of the side parts of the trolley-head appurtenant to the slots c3. The head may be provided with the usual conducting-pieces d, extending downward from the axle or spindie c into the hollow body part of the head. When these conductors are employed, the upper edges are provided with slots so arranged with respect to the slots a3 that the axle may be inserted therein. These conductors preferably extend a short distance above the axle. Washers c, commonly used in this form of device, may also be employed, if desired, these washers being placed on the axle, so that they will be removed or replaced therewith in the head.

A latchf is pivoted to the trolley-head in a manner to retain the axle or spindle c securely in place. In the preferred form of the invention and as shown herein this latch is formed to U shape, each branch being located app urtenant to a side part of the trolley-head. The outer ends ot' each branch are bent at an angle to the opposite end of the branch, and these ends are pivoted at f' to the side parts of the trolley head. A recess f2 is formed in the latch of a shape to receive the axle or spindle c. When the latch is in position to hold the axle in place, the latch lies, preferably, Wholly within the depressions or recesses a2, so that no projecting parts or uneven su rfaces are presented to be caught upon a trolley-wire or the like.

The lower part or cross-bar, preferably, of the latch is provided with a spring-catch g, suitably constructed and arranged to hold the latch securely in position.

In a device embodying my invention and constructed as herein illustrated and described I have provided means whereby the trolley-wheel and its spindle may be readily removed or replaced for any purpose; but I do not desire to limit myself to the precise construction herein set out, as it is obvious that the 'details may be departed from to a considerable extent and even the essential IOO features altered without departing from the scope of the invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a trolley-head, in combination, the side parts having slots for the reception of the trolley-wheel axle, the trolley-Wheel axle supported in said slots and bearing a tro1leywheel, and a latch arranged to lie across the slots to hold the axle in position.

2. In atrolley-head, in combination, forked side parts having slots for the reception of the trolley-Wheel axle, the trolley-Wheel axle supported in said slots and bearinga trolleywheel, and a swinging latch pivoted to the the forked side parts having slots for the reception of a trolley-wheel axle and recesses on the inner surface of the side parts for the reception of a latch, a trolley-Wheel axle loi cated in said slots and bearing a trolley-Wheel, and a latch pivoted to the side parts of the. trolley-head and arranged to extend across said slots to hold the trolley-Wheel axle in position.

5. In a trolley-head,in combination with the forked side parts having slots in the upper edge thereof for the reception of a trolleywheel axle and recesses along the inner sur.- face of the side parts for the reception of a latch, a trolley-Wheel axle bearing a trolleywheeland located in said slots, and a latch having branches pivoted to the side paris of the` trolley-head and arranged to lie within said recesses and also to project across said slots to holdlhe trolley-Wheel axle in position, and means for holding the latch in its closed position.

6. In combination in a trolley-head, side parts havin'g slots for the reception of the trolley-Wh eel axle, cond ucting-pieces secured to the side parts and having slots for the reception .of the trolley-Wheel axle, the trolley- Wheel axle arranged to be supported in said slots, and a latch arranged to extend across a slot to hold thetrolley-Wheel axle in position.

7. In a trolley-head, in combination, side parts arranged to su pport a trolley-wheel axle, the trolley-Wheel axle `supported by said side parts and bearing a trolley-wheel, and a latch arranged to extend across the axle to holdit in position.
